Abstract
The utility model relates to the technical field of machining operation and provides a deep hole drill bit which aims at overcoming the defects that the known existing drill bit is expensive, and an cutting edge can not be ground easily, so that the known drill bit is not ideal. The deep hole drill bit can achieve the purposes that the cost is saved, the manual grinding is realized, and the manufacturing is simple and convenient. A technical scheme for solving the technical problems is as follows: the deep hole drill bit consists of a deep hole drill, a drill rod and a drill stock, and is characterized in that one end of the hollow drill rod is welded with the deep hole drill, the other end of the hollow drill rod is welded with the drill stock, the drill stock is provided with a gas-liquid conveying hole communicated with a central hole of the drill rod, the deep hole drill is provided with a gas-liquid output hole communicated with the central hole of the drill rod, and the central hole is directly communicated with a groove of a cutting edge. When the deep hole drill bit is used, a machine tool jig tightly clamps the drill stock, and the drill stock or the drill bit is communicated with a gas-water pipeline, so that the condition that the temperature is reduced, and scrap iron is smoothly discharged when the drill bit works can be ensured.
Description
Technical field
The utility model is related to a kind of machining class technical field.
Background technology
At present, known existing drill bit is expensive, and the bad sharpening of cutting edge.It is not ideal.
The content of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of deep-hole drill bit, with regard to that can reach saving cost, can hand grinding, the easy purpose of manufacture.
The technical scheme in the invention for solving the technical problem is：The deep-hole drill bit being made up of deep hole drill, drilling rod and drillstock, it is characterized in that：Hollow drill one end is mutually welded with deep hole drill, and the other end is mutually welded with drillstock, and the defeated hole of the gas-liquid communicated with drilling rod mesopore is provided with drillstock, and deep hole drill is provided with the gas-liquid delivery outlet being connected with drilling rod mesopore, and mesopore leads directly to the groove of drill edge.Drillstock is clamped with jig when using, air water pipeline is connected, it is ensured that cooling and smooth discharge iron filings during bit operation.
The beneficial effects of the utility model are：Simple in construction, easy to use, reduction drilling deep hole cost, and oneself manufacture and grinding drill lip effect are good.
